I used vobsubmod to combine .srt subs with an .avi file for the first time. There were two seperate .srt subs and .avi files, part 1 and 2. It went from about 700 MB to 500 MB for each combined file. I selected Xvid because there were 2 DivX options for video compression and I wasn't sure which was better. I was getting an unable to open message from TmpEnc 3.0 as I try to encode the new .avi file. Due to someone having this problem and Praetor's suggestion (http://forums.afterdawn.com/thread_view.cfm/57227) I went through the codec faq and uninstalled/reinstalled my codecs so I am sure I have the updated codecs. Any help getting these encoded to dvd would be appreaciated. They do play fine on my computer as well.
